No. 91 Lees.

To all "whom 'it concern: ,f Be it known that I, FRANK WooDnEAD, acitizen Aofthe United States, residing at Cheltenham, county of -Montgomer and State of Pennsylvania,'have invente a certain new and useful Improvement in Pumps,

' of which the following 1s a specification'.

My invention relates"to a new and useful invention-in pum s and has for itsfobject to rovide an eXcee ingly simple andy-effective evice of this character -by-means of which the power of a self propelled vehicle will be usedto o erate thepuinp forinflating the tires or w eels of said vehicle. v

With these lends in view, this invention consists'in the details ofconstruction and which this inventionappertains may underthereof.

combination of4 elements hereinafter set 'forth and then specically designated bythe claims.

In order that those skilled in the art to stand how to .make an use ,the same, I willl describe its'construct-ionin detail, referring by letter to the accompanying dran ing forming a part of this specication, in which;-

` :Figure 1 is a side elevation of my improved pum showing the wheel of the vehicle .to whic it is attached. Fig. .2 is a planview securing the crank bracket to the wheel, said bracket being broken away,

In ca .rryingA out my invention as here embodied A represents one of the drivenwheels of a self propelled vehicle whichis raised up from the ground .by means of a lifting jack B. To the spokes of their heel is secured the crank bracket Oto the 'outer' end of which is secured the crank D( 'I'he bottom portions of the legs of the crank bracket C are bent so 'as tol `form the feet E and these feet have the o enigs F'form'ed therein,- through which t e curved bolt G is adapted to pass, the curved end thereof engaging with one of the spokes of the-heel A. 'lhe thumb nut H is then threaded onsaiil curved bolt lthus holding -the crank bracket to the'wheel'. l On the central shaft ofthe crank bracket 1s secured one end [of the rod vI the opposite end being fastened to one end of the hanger J, the opposite endof said'hanger being movably securedto the stand l of the rodAIin proximity to that end vhich is'securcd.

'Io the hangerJ is pivoted the pump L as indicated at M. lhe outer end of the plun-` ger rod N of the pump L is secured to thespecincation or Letters Patent. Applicationled Mayl 11, 1908. Serial No. 432,057,

lfree end of the crank so that When'the wheel is lturned the plunger rod. Nwill be caused. to reciprocate, thus turnm'g the -an` lfrom the pum through' the flexible hose O' intothel tire o either of the Wheels of the vehicle towhich the hose'may be attached and when these .tires are inflated the pump can be removed through the other drivenw-heel of 'the vehicle, in this. way inflating thel tire of the wheel to which the pump was first attached. 4

vIn practice one of the rear driven wheels of the self propelled vehicles would be lifted up by means of the lifting jack and the crank bracket C secured to the spokes of this lifted'wheel by. means of the curved bolt G and the thumb n ut'H, the power would then 'be applied to thisraised wheel the differential gearing' allowing it to revolve, which would caus the crank D- to also revolve, thus reciprocating 4theplunger rod N to the 'lathe pump being pivoted to the rod allow it to move up and down,l thus followin the movements of the crank I).

provide the stand and hanger to which the rod J is connected to the bracket inthe '.motion ofA the brace rod in case the wheel is not true or if the crank bracket is not set on the spokes of the wheel.

One of the large advantages of my improvenientis lthat it requires no special attachments whatever upon the car on which it is tob'e used. y l l 0f course I donot wish to be' limited, to the exact details here shown as these'inay be varied within certain limits without depart ing from the spirit of my invention.

Having thus fully described my invention, i .what Iclaim as new and useful, is-

1. In combination a crank bracket, the legs of which are bentfto form feet having openings therein, curved, bolts adapted to.'

pass through said openings, and fit about the- .of the crank when the wheel to which the crank bracket is secured is revolved and a dit I dk) .ilexi'ble hose for conveying the air from the the crank so that the suine muy be rvcipro- 1U pump to the tire vwhich is to be nated as cated as shown' and described. shown and descrihcd.
